It is not possible to construct an engine that does nothing but convert heat into useful work.
If some of the heat must go into raising the temperature of a sink, not all of it can be converted into work.
If work is being done by the heat engine, the object on which work is being done is not isolated from the heat engine. Unless it is at the same temperature as the heat source, heat will flow conventionally from the heat source to the object on which work is being done, and the object's temperature will rise.
